The Petzl Tandem Speed Pulley is a climbing pulley for lower-angle tyrolean traverses. The Tandem Speed Pulley uses stainless steel sheaves for durability. The fastest transport pulley by Petzl, at a maximum allowed speed of 20 m/s. ZOOM! The sheaves are mounted on sealed ball bearings for sustained speed. The pulley is capable of transport via rope or cable and can attach up to three carabiners. Enjoy sending yourself (or a buddy) across to the other side.

Its scary FAST!I had built some zip lines before and used just a standard rescue pulley and they went pretty quick, but when i put this pulley on it was scary how fast we went and stopping became a major issue. You don't need much drop at all to have a good zip line with this pulley (about 10 feet drop per 100 feet run). ,,,,The only down side is it can be difficult (but doable) to bend a rope (mine is a 11 mm static) through the top part between the two wheels for the advanced hauling mode.,,

Solid, Stable, Reliable, FastUsed this for a youth zipline with a cable in COLD weather... It worked beautifully. Stainless steel construction and Petzl build quality makes this rated tandem pulley a great value. Clip-in point handles up to 3 caribiners which is useful for varying configurations and uses.

A great pulleyI've always used this pulley for zip lining. I know its not designed for that, but it works perfectly for that purpose. Since it is classified as a speed pulley, it works great. Runs smooth on the line!

Easy to useIt is a great and durable pulley. I use it on cable (12 mm diameter) and on rope (13 mm diameter)with no problems, mostly in theathers, for flying effects. Works great!
